Possibly the tribunals were an addition due to the Holconii. The corridor under the gallery, however, must have been built in the place of an earlier corridor, for the piers on the outside rest on foundations similar in character to the oldest parts of the building. As these piers served no other purpose than to sustain the passage opening into the section of seats above the corridor, this must have formed a part of the original plan. The statues of both the Holconii probably stood in niches in the wall at the back of the stage. Holconius Rufus was further honored with a monument of some sort in the cavea. The lowest seat of the media cavea had at the middle, directly opposite the stage, a double width for a distance of about five feet, gained by removing a portion of the next seat above. Here was an inscription in bronze letters: _M. Holconio M. f. Rufo, II. v. i. d. quinquiens, iter[um] quinq[uennali], trib[uno] mil[itum] a p[opulo], flamini Aug[usti], patr[ono] colo[niae], d[ecurionum] d[ecreto]_,--'[Dedicated] in accordance with a decree of the city council to Marcus Holconius Rufus the son of Marcus, five times duumvir with judiciary authority, twice quinquennial duumvir, military tribune by the choice of the people, priest of Augustus, and patron of the colony.' The object placed here was of bronze, and was made secure by fastenings set in twelve holes; what it was is altogether uncertain. The ancients had the custom of conferring lasting honor upon a deserving man after death by placing in the theatre a seat inscribed with his name. We should be glad to believe that a 'seat of double width,' _bisellium_, the use of which was allowed to members of the city council, was placed here, but the arrangement of the twelve holes is difficult to reconcile with this explanation. The architect employed by the Holconii, a freedman, was not honored with a statue, but his name was transmitted to posterity in an inscription placed in the outer wall near the east entrance to the orchestra: _M. Artorius M. l[ibertus] Primus, architectus_,--'Marcus Artorius Primus, freedman of Marcus, architect.' The plan of the Theatre could not have been taken from a Roman model; it conforms, as we should have expected, to the Greek type. In the Roman theatre the orchestra was in the form of a semicircle, of which the diameter was represented by the stage. In Greek theatres, on the contrary, the stage according to Vitruvius was laid out on one side of a square inscribed in the circle of the orchestra; the orchestra, as shown by existing remains, in most cases was either a complete circle or was so extended by tangents at the sides that a circle could be inscribed in it. The latter is the case in our Theatre, of which the orchestra has essentially the same form as that of the theatre of Dionysus at Athens.
